Serial number is on the case: i remember buying it a long time ago from a forum member and having to fill in a form downloaded from Adobe to transfer registration. I did fill it in and send it away, never got anything back from it. Never had any issues installing it or using it, I guess it's just if you want to register it with Adobe.

Figured rather than binning it, it might be of value to some of the users here running older machines. Don't think it's worth anything now-i'm actually saving up for a leather case for my iPhone so trying to get some pennies towards that, so call it £10 all in? I suspect most of that will be postage so i'm not fussed about a huge profit!
